,spring42 isvreceived'in aA retainer '43.' The `retainer 43 is engaged by an adjustment screw 45, which is threadedly retained by'v 'beris provided in theform of a projection or nozzle 5() which surrounds an opening 51 constituting the inlet of theinvention. f

The bodyv 3() is Valso provided with a threaded outlet opening 54 to which suitable hose connection lor `equivalent may be at tached.

Adapted toeclosejthe inlet 51'lis'alvalve 56. Thevalve' includes a-thimble57 having a cylindrical opening which isolosed at .I

one end. Extendinginto the'cylindrical opening is the nozzle 50. Supported.l at the closed end of the thimble 57 is -a valve mem` ber 58 adapted to engagea seatv59 lformed on the end ofthe nozzle'V 50. Openings 60 are formed in the cylindrical wall of theV thimble 574so that when the valve member 58 is disengagedfrom theseat 59V gas under Vpressure'maypass' into thecharnber 38.:` At

the right end of the thimble 57, as shown in Fig. 1, is anannular ilange 62.v Placed between the flange 62 and the adjacent wall ofthe body 43() is a friction compensating spring 63. j

The thimble 57 isA adaptedvto be engaged l by a power strut 65 which isv preferably formed from a' single piece of resilient metal and in form. and action constitutes a toggle which longitudinally expands# as it vis straightened. The end of theV power strut which engages ithe thimble 57 is bifurcated y so asY to form a .central pocket 66, thebifurcations 67 extending on opposite sides ofthe thimb'le 57 and engaging in slots 68 formed 'in' the iange 62.

The oppositeend off'the pow-erstrut65 gages an adjustment4 member 69,? which is threadedly received ina threaded pocket `7 0 Vformed -in the body 30..I vThe power strut has atongue7 2 which projectsinto anopeni Ving f7 3 of the 'adjustment member and*V has faces 7 4 which engage an end face 75 ofv the` :adjustment member. Y.

' f Extending downward from thev diaphragm 37 -is a clamp .77.V This stirruporclamp 77 is vrigidly vsecured to .theV diaphragm by means ofv the' bushing 39; i'lhelowerend of the'clamp 77 yhas aiicentraly channel l7 8 whichis -Y open at! the bottom." Extending Vloo `on opposite sides ofthe channel 7 8 are `legs f 79 which define it. Y They legs V79V extend on opposite sidesfof the centraljportion of the ,i power strut 65. Extending'a'cross the channel and engaging' inv recesses 80lformed on the inner. `faces ofthe legs-79y is a T'key 81.

The key 81 retains theV power strut 65fin the l V kchannel 78 vin definitev relationV thereto.'y vThe key l81 cooperates with the bottom of the channel 78 to form a pocket orl opening 82through which the power strut 65 is-.extended. Y L l The clamp Y77, the power strut 65- and the vparts 'associatedl therewith constitute the 'op-l eratmg means of my invention connected to the pressure-responsive -means or `dlaphragm 37 and to the; valve. -The clamp I which Aconnects the power'strut. to vthediaphragm.

'is f I have describedthose parts of vmy 'ijnvention which are common tothe for-ms of the'invention shown in Figs.` l to 2l incluthose features of construction which are pe# culiar to each form of the invention.; -It shall be understood, therefore, that the numerals 30 to 82 inclusive apply to each form of the invention shownin Figsql to 2l in# elusive. f`

4Referring now particularlyto Figs. l Vto 6 inclusive, the'cla-nip 7 7 is providedwith the channel 7 8, the upper wall 85 of which is-inclined. By inclined I mean that the Ywall 85 is at an angle to a perpendicular of a line fi-A of Fig. 5, which is parallel to the plane of motion of the clamp 77. i o C In this form of the invention it is desired to cause'the valve 56 not only `to pressurally engage theseat 59 but also to be rotated if necessary to form a complete closure. f The operation of this form of the invention is substantially as follows: `Assume that the parts are in the position shown in Figs. 1,2, 3, 4, and 6. v'Ihe operator advances the-adjustment screw l5' downward so that the diaphragm 37 isinoved downward and theclamp 77 moved downward along Vthe axis A-A- It will be evident. that since the left edge of the inclined wall 85 (reference being had to Fig. k5) is lowest, the left edge of the power strutV will be engaged. 'This engagement causes the entire power strut '65, adjustment member 69 and valve 56 to rotate from the position shown in Figs; 1,2, 3, 4l, and 6 into sueha position that thepower strut occupies aposition shown lin full linesA in Fig. 5. In this position the upper face `of the power Vstrut 65 lies in a plane parallel to the -wall 85. The portion of the power strut 65 extending through the opening'82lias moved from dotted line position 88 into fullline position in Fig. 5.

When thediaphragm 37 and the clamp 477 are depressed. the central portion of the power strut is moved downward'with the result that the right end thereof moves towards the center, and 'this'allows the valve 56 to be moved from seated position. The inlet 51 `is then opened and gas under pressure will pass into the chamber 38.v As pressure builds up rin the chamber 38 the .diaphragm is gradufally moved upward against the action of the regulating means, which forces downward against it, and the clamp 77 vis moved upward. VvThen the clamp moves upwardthe power strut tends to straighten of'its` own accord. As previously pointed out the power strut is made from a resilient metal and therefore it cord with the clamp 7, thus movingtlievalve vted lines 88.

ftawards its Seats; `It iS important t9. 9b# ser-ve that ,dur-111e' this operation .the teatral por-tion of the power strut is notrforced `upward Vby the key 8l. When the partsmove upward tothe extentthat the valve56 lvhas g:

seated, the yinflow of` gas to theV chamber'jS-,S will-be arrested, if the valve forms atight seal.. y .l

' However, ifthevalve does not form a tight seal for the i'easonfofimperfect seating, which Amay be causedby -various things, for example,

the presence of a particle of foreign material between the valve member 58 and tlieseat `59,

gas will continue to leak inthe chamber 38' and the pressure will bebuilt therein. VDue to this increase in pressure aft-er seating of the rvalve"56,dthe diaphragm and theO clamp continue to move upward.

Due tothe fact that `theseating of valve 56 i prevents the power strut from* 4further straightening `offitsown accord,`the key 81 comes into Contact with the power strut and rotates'it from the positionwshown inv full lines in F ig. 5 int-o the vposition shown by. dotrhe result of this ,action vis/to E turn the valve-56 while .it isin pressural eontact with thes'eat 59.v VThis combinationoif pressural force and rotative force iseffectivek in disposing of th-e foreign particlelwhichv prevents the valve from forming Aa perfect.;l

seal `or disposes of any condition` whichprevents this perfect seal. v It is `desirable tohave the adjuster o 69 restrained from rotation. This may be laccomplished `by the threads thereofand-of the openingL arather close fit, so thatthefriction will prevent the adjuster from rotatingL with the-strut."v 'Ihis may also he accomplished by placing a washer l between the ,strut andthe adjuster.

In theform of the nventionuwhich I have.

after the valvereaches its seat. I have fob- 1,95 .just discussed it will'be seen lthat. the rotative" action is accomplished by the connecting` means engaging the powerstrutinsuch a.

served that very often `the power strut is ro-y tated during `the seating of the valve. I therefore donot wish to he limited toa construction in-whichthe rotation occurs only after the valve has seated. lThe rotation may occui' slightly before, during, and afterseating of the valve. Y Y In the form of my invention show n in Figs.

7 and 8 the clamp 77 is providedV with laV central bearing 90 1which depends downward from Y the `upper wall of. the channel78 on theaxis ing 92, which is offset fromthe aXisA+A7-aS gaged Iby the-central bearing 90.` which is .on'

the axis `A-A.. Inother words, :thecentral partof the :power strut 65 is engaged; and no y open', pressure will buildup in the chamber fis ' Y that the power strut l65 is engaged eccentri- Y callyV of its .center of'rotation so that the 1 power 'strut and the valve 56 will be rotated.

"er strut 65. --Both ci the central bearings 95 v; and 96 are provided on the axis A-A of the ll .there will be no appreciable 'relative up and 38, and the diaphragm and clamp will move upward. The power strut moves Vupward Vof' its own accord until the valve is seated, and then if a perfectseat is not formed there will be "a leakage and anincreased pressure in the chamber 38. -As the clamp 77 continues to move upwardthe offset bearing 92 engages vthe power strut 65 eccentrically of its center "of rotation with theresult vthat the power :strut is swung from full'linefposition in Fig. V8 into dotted line Vposition 93. This causes a rotation of the valve V56, which, as previous- "lyk explained,`is effective in disposing of they vcause.forleakage of gas into the chamber 38. In-this former the invention it Ywill be seen In'the form of the invention shown in Figs. 9 to 12 inclusive the *clamp 7 7 Vis provided with a central bearing 95 'which extends downward to engage the power strut 65, and the key 81 is provided with a central bearing Y96,'which extends upward to engage the powfclamp'77. The distance betweenv the Vcenjtral bearings 95 and '96is substantially'that Yward as a'result oran' increase in pressure in the chamber 38 the power strut will straighten of the thicknessof the power strut'65`, so that down movementbetween the powerstrut and the clamp. As best'shown injfFig. 12, the end ofthe'l power' strut 65 which engages theV face 75r-o'fthe adjustment member 69 is provided with'fa side face 97 which engages the face 75 and isprovided with anangular side tace 98, Awhich is ordinarily 'out of engagement with the face 75".V VIn the forms of the invention shown in Figs. 1 tcl8 inciusivethere has been contact between the power strut and the I. `adjustment member 69onfbo`th sides of the yaxis A-#A and el j tongue. 72, :so that the center of rotation or the power strut is the geometric centerorit. In the form of the invention now being described, due to lthe fact` that there is contact Yon one sideof the lpower strut at the end which engages the adjustment member 69,

V-thecenter of rotation of the power strut is in the plane indicated by the line B-B. It will Ybe .seenv that where the line B-B passes through the opening 82 of the clamp 77 the areoifset.

' 4'comes seated.` Therefore, Vif there isa leakage'of gas into the chamber 38 the clamp 7 7 `will move upward and the power strut will 'be engaged Y"by the central bearing" 96 of the fkey 81. Due to the fact that the central bear- Ving'96 engages the power strut 65 eccentrically of its center or rotation B-.B the power .strut will be Vrotated in a clockwise direction in Fig. 9." The powervstrut and the valve 56 Vnates anything which has caused the center of rotation B-#B '17 inclusive.'

will rotate together with the same result as in the forms of my invention lpreviously described. It will be seen that in this'jform of the invention the rotative action is obtained by the designing of the power strut so that kthe center of rotation is swung `out'voi aligny rment with the axis A-A.

In the form oi the invention shown in-Figs. 13 to 17 inclusive the clamp 77 and the key 81 are constructed as in Figs. 9 to y12 inclusive, being provided with central' bearings 95 and k96, which are formed on the VaXis'A-A of 99 is deeper than the slotV 98,v with theresult that one or the fui-cations does not engage the lthimble 57. In view of this eccentric enf gagement "of the Yvalve end of the power strut 65, the center of rotation of the power strut is oiiset from its geometric center andV is indicated by the line C'C.

ll/Vhen the diaphragm and clamp move upwill beengaged by the central .bearing 96.

C--C of the power strut 65 is :eccentricall-y disposed andV is not intersected bytheaxis AeA, the centralbearing 96 .will engage the powery strut eccentrically of itslcenter of ro tation and causel itiv toV rotate from the position-showny in full lines in Fig. 17 into al posi* tion indicated `by dotted lines 100. This causes the valve 56 to rotate, with the result that thevalve rotates on the seat 59 and elimiimperfect seating ot'the valve. .f

'InFigL 18 I show a fragmentary view illu`strating janothertormV of the invention. In this form of thefinvention the furcations 67 extend into slots 102 of the flangev 62 of the thimble 57, whichslots102 are of the same depth.' One furcation 67, however, which I indicate bythe numeral 103 is Vshorter than 'the-other with the result that there is engagementk only on one side of the thimble 57 This Vhas the sameeftectas making one slot inthe flange 62 deeper than the other and consequently the axis Yof rotation of the power strut is made eccentric. This i'orm of the invention' operates in the same manner as the form or the invention shown in Figs. 13 to tinue `to moverupward and the power strut -Due tothe factnthat the center offrotation In Figs. 19 to 21 inclusive, the lower end of the bonnet spring 42 isprovided with an end 104 .which is not parallel with the upper end 105 thereof. This causes the diaphragm to be swung so that the axis A-eA is swung from a perpendicular position.. The channel of the clamp 77 is provided with a top wall 106, which is perpendicular to the axis A -A- The key 81 is provided with acentral bearing 107 which engages the power strut so that the power strut is clamped against the top.A wall 106. In the operation of this -form of the invention the twisting or rotation of the Y valve is accomplished by virtue of the fact `that when the diaphragm is 4moved by the pressure in the chamber -38 the `clamp 77 swings so that the axis A-A assumes a Ydiffiferent position. Y

In other words, when pressure in the chamber 38 builds up, the axis A-A may move',`

from the position shown in full lines .into the position indicated by the dotted line A-D. It will therefore be seen that as a result ofv the swinging of the ycla-mp 77 the power strut 65 will be swung-so as to rotate the valve 56.y

' In Figs. 22 and 23 I illustrate my invention applied to the form of pressure regulator now in ygeneral use. In these figures the numerals previously .utilized are not applied. Referring to these figures, this form .of the invention comprises a body 111'having a cavity 112,-the-upper portion of'which is .closed by a diaphragm 113 secured in place by means of a bonnet 114. Adapted to press against the diaphragm 113 are springs 115.- Y The pressure of the springs 115 against the diaphragm is controlled by an adjustment screw 116. Extending into Vthe cavity 112 is an arm 117 having an inlet 118 formed therein. T-hieadedly secured to Ithe inner endiof the ar1n`117 on an axis concentric with the cen-1 ter ofthe vdiaphragm 113 isa nozzle 120 having a seating face 121.

The plate 127 has a. lower cavity -128 into which a' centralizing Aprojection 129-.of thev body may extend. y.

' Formed inthe plate concentric with .the axis'ror center line of thezdi'aphragin 113 is a cavity 130.
